Car Idles good in park And neutral. If you put it in drive the rpms start to climb. You put it back in neutral or park and it goes back to about 850 rpms. Base Idle is between 350 and 400. Checked the resistance of the IAC it was 10.1. Your advice thanks

I had a spare IAC put it on and it did the same thing. Also with the TPS. I don't have the car at the moment.

You only have a possibility of 0 to 12 volts. Are you on the right scale?
